Full-Duplex Massive MIMO Multi-Pair Two-Way AF Relaying: Energy Efficiency Optimization
TL;DR: This work considers two-way amplify-and-forward relaying, where multiple full-duplex user pairs exchange information via a shared full- duplex massive multiple-input multiple-output (MIMO) relay, and maximize the non-convex energy efficiency (EE) metric by approximating it as a pseudo-concave problem, which is then solved using the classic Dinkelbach approach.

OTFS Channel Estimation And Data Detection Designs With Superimposed Pilots
TL;DR: Two channel estimation and data detection designs for SP-OTFS systems which, unlike the existing OTFS designs, do not designate any slots for pilots, and consequently have higher spectral efficiency (SE) and are numerically validate the derived analytical results.
Journal ArticleDOI
CFO and Channel Estimation for Frequency Selective MIMO-FBMC/OQAM Systems
TL;DR: This letter estimates carrier frequency offset and channel in multiple-input multiple-output (MIMO) filter bank multi-carrier systems based on offset quadrature amplitude modulation using a novel frame structure and develops minimum mean square error estimator for effective channel estimation in time domain.

SER Analysis of MMSE Combining For MIMO FBMC-OQAM Systems With Imperfect CSI
TL;DR: It is shown that the PP-SNR, derived by assuming imperfect receive channel state information, accurately characterizes the symbol error rate (SER) of MMSE combining in MIMO FBMC-OQAM systems.
